In order to explore the diagnostic value of spiral CT and magnetic resonance imaging scanning in gastric cancer and precancerous lesions, the author selected 56 gastric cancer patients treated in a medical center (group) as the experimental subjects, and all patients underwent MRI, multislice spiral CT scan, and enhanced CT scan two weeks before surgery; at the same time, the gastric cancer staging results of patients were diagnosed according to surgical pathology. All patients were examined under the condition of knowledge and performed breath-holding exercise before examination. The status, location, and extent of tumor lesions were evaluated. In comparison of T staging of gastric cancer patients with magnetic resonance scanning imaging and postoperative pathological examination results, among them, T staging of 3 patients did not match the results of pathological examination, the accuracy rates of T staging on magnetic resonance scanning imaging were T1 = 94.7%, T2 = 87.6%, T3 = 91.2%, and T4 = 94.7%, and the total accuracy was 92.1%. Comparison of helical CT scan imaging and postoperative pathological examination results is as follows. Among them, T staging of 8 patients did not match the results of pathological examination, 3 patients were ulcerative, 5 were protuberance, the accuracy rates of T staging in spiral CT scan imaging were T1 = 90.8%, T2 = 82.2%, T3 = 76.9%, and T4 = 87.6%, and the total accuracy was 84.5%. The total accuracy rate of imaging N staging was 77.5%, and the total accuracy rate of spiral CT scanning imaging N staging was 80.8%. The accuracy rates of M0 and M1 staging in magnetic resonance imaging were 100.0% and 96.5%, respectively, and the accuracy rates of M0 and M1 staging in spiral CT scan imaging were 96.5% and 96.5%, respectively. The accuracy rate of magnetic resonance imaging for the diagnosis of gastric cancer N staging was 77.4%, and the reason for the low accuracy rate was mainly because the enhancement effect was not obvious due to insufficient enhancement. The accuracy rate of spiral CT in diagnosing N staging of gastric cancer was 80.9%, which was mainly due to the small diameter of the middle celiac artery lymph nodes. Magnetic resonance and spiral CT scans have high value in the early diagnosis and staging of gastric cancer.

In order to observe the effect of MRI image scanning on shoulder pain caused by volleyball training injury, this paper proposes to analyze the value of MR arthrography and conventional MRI image scanning in the diagnosis of shoulder injury. Taking the female volleyball players in a no. 1 middle school for nearly ten years as the research object, the injury investigation and statistics were carried out. The shoulder joint injury was investigated using arthroscopy and no injury was found. All patients underwent MR arthrography and routine MRI image scanning after admission. All patients underwent MR arthrography and routine MRI image scanning after admission. The patient took the flat lying position and put their arms flat on both sides of the body, and the Philips Achieva 3.0T MRI image scanning and Sense Flex M soft coil for MRI image scanning detection were used. The plain scan included oblique sagittal, axial, and oblique coronal proton density weighted image sequences; echo chain ETL = 6, TR/TE 2300/25 ms; and oblique sagittal and oblique coronal SET1W1; TRTE is 400/10 ms. Comparison was made with regard to the sensitivity, specificity, Jordan index, and accuracy of MR arthrography versus conventional MRI imaging in the diagnosis of shoulder injuries. The results were 38 true positives, 19 true negatives, 1 false positive, and 2 false negatives; a normal MRI scan showed 33 true positives, 13 true negatives, 7 false positives, and 7 false negatives. MR arthrography is more accurate than MRI image scanners in the diagnosis of shoulder injuries.

In order to solve the problem of cervical spondylosis in the early stage of various cervical spondylosis, effective treatment can prevent the deterioration of the disease. This paper presents the results of a clinical trial examining magnetic resonance imaging in the treatment of cervical spondylosis with flotation therapy and selected 68 patients with cervical spondylosis. According to research commodity, using a rigorous randomized controlled trial, 34 cases were divided into a control group (acupuncture group). The needles were kept for 30 minutes once a day. The treatment group (acupuncture combined with floating acupuncture group) was treated with acupuncture on the 1st, 3rd, and 5th days and floating acupuncture on the 2nd, 4th, and 6th days, respectively. Both groups were treated for 6 consecutive days and rested for 1 day. After 2 weeks of treatment, the simplified McGill Pain Scale (MPQ), visual analogue scale (VAS), and neck pain scale (NPQ) were observed and recorded to compare the curative effects. Finally, Excel software is used to manage the data, and SPSS21.0 is used for statistical analysis. Measurements of gender, age, disease, VAS, simple MPQ, and NPQ of the two groups were compared in the two groups, > 0.05, which was not significant and comparable. After treatment, VAS, simple MPQ, and NPQ of the two groups were compared in and between groups, the total < 0.05, with the mean data. . Acupuncture combined with float needle and acupuncture therapy can improve the pain and breathing of cervical spondylosis and improve the quality of life of patients, but acupuncture combined with needle float is more pronounced than acupuncture groups.

Mitochondria are versatile organelles and function by communicating with cellular ecosystems. The fluorescent colocalization analysis after fixation is a highly intuitive method to understand the role of mitochondria. However, there are few fluorescent dyes available for mitochondrial staining after fixation. In this study, a novel fluorescent dye (BO-dye), extracted from , was applied for mitochondrial staining in fixed immortalized human oral keratinocytes. The BO-dye (excitation: 414 nm, emission: 677 nm) is a small fluorescent molecular dye, which can cross the cytomembrane without permeabilization. We assume that the BO-dye could aggregate and bind to the mitochondria stably. BO-dye exhibited a mega-Stokes shift (>250 nm), which is an important feature that could reduce self-quenching and enhance the signal-to-noise ratio. Analysis of photophysical properties revealed that the BO-dye is temperature and pH insensitive, and it exhibits superior photostability. These results indicate that BO-dye can be considered an alternative fluorescent dye for labeling mitochondria after fixation.

In order to explore the value of color Doppler ultrasonography (TVCDS) in the diagnosis and differential diagnosis of adenomyosis. A total of 150 patients with adenomyosis admitted to a hospital from January 2020 to December 2021 were selected, taking transvaginal three-dimensional color Doppler ultrasound and abdominal ultrasound for examination, all results were compared with patient pathology or surgical results, in order to compare the accuracy of the two inspection methods. The positive predictive value of three-dimensional color Doppler ultrasonography was higher than that of abdominal ultrasonography, and the difference was statistically significant ( < 0.05). The coincidence rate, sensitivity, and specificity of three-dimensional color Doppler ultrasonography were higher than those of abdominal ultrasonography, while the misdiagnosis rate was lower than that of abdominal ultrasonography, and the differences were statistically significant (all < 0.05). The imaging features of vaginal three-dimensional color Doppler ultrasound in patients with adenomyosis are mainly enlarged uterus, slightly stronger echoes in the myometrium with enhanced echogenic spots, and short or short branch blood flow signals in the lesions. After statistical analysis, there was a significant difference in the blood flow changes between benign and malignant endometrial echoes and abnormal echoes in the uterine cavity, < 0.05. Normal endometrium and benign intrauterine lesions mainly showed no blood flow signal, while malignant lesions in the uterine cavity mostly showed changes in blood flow signal. Compared with abdominal examination, transvaginal color Doppler ultrasonography has obvious advantages in the diagnosis of adenomyosis. According to the characteristics of ultrasound images, blood flow distribution, frequency spectrum, etc., it can provide a more accurate basis for clinical timely, provide the identification points of uterine fibroids, and provide help for clinicians to choose a treatment plan.

The study goal is to solve the problem of the diagnosis of triceps crus injury of volleyball players, meet the needs of volleyball players and team doctors for the correct diagnosis of triceps crus injury scanning, make up for the deficiency that triceps crus injury scanning diagnosis is easy to make mistakes, and improve the efficiency and ability of triceps crus injury diagnosis scanning. Because the experiment involves the technical action of volleyball jump serve, DELSYSR Trignomobile wireless portable surface electromyography tester (16 leads) made in the United States is selected to test the surface electromyography of the main muscle groups of college male volleyball players in the process of jump serve. The German made simi-3D motion image system is used to conduct three-dimensional synchronous test of athletes' jump serve action. The data analysis software adopts EMG work analysis, EMG analysis software, and simi-3D motion image analysis system for postprocessing data. The original signal is filtered (400 Hz for low pass and 20 Hz for high pass) and rectified. Finally, IEMG, EMG contribution rate, and RMS were calculated. This ensures the accuracy of the experiment.

In order to solve the problem of scanning magnetic resonance imaging in prenatal diagnosis, the application and research of placental implantation have been proposed. Placental implantation is a serious obstetric emergency, which refers to the abnormal attachment of placental villi caused by the dysplasia of decidual basal layer. A study from the United States showed that the incidence of placental implantation in pregnant women during delivery increased from 9.9/30000 to 11.6/20000 from 2006 to 2019, which increased the risk of prenatal or postpartum hemorrhage, hysterectomy, stillbirth, abdominal organ injury, and so on. Clinically, patients can show severe prenatal or postpartum hemorrhage, postpartum placental retention, uterine perforation, and secondary infection, which may seriously endanger the lives of pregnant mothers and fetuses. Placental implantation can also have no obvious symptoms before delivery, which leads to insufficient prenatal diagnosis. Gielchinsky retrospectively studied 410 patients with placental implantation and found that only 9 patients were detected by prenatal ultrasound or magnetic resonance imaging (MRI), and the detection rate was only 6.6%. It can be seen that if the accurate diagnosis of placental implantation can be made before prenatal or symptoms appear, clinical intervention treatment can be carried out in time to reduce the probability of hysterectomy and improve the examination means of patients' prerecovery. At present, studies at home and abroad suggest that it has good clinical application value and research prospect in the clinical diagnosis of placental implantation.

Detection of arterial stiffness is an important method to predict the occurrence of hypertension complications and to screen patients with high cardiovascular risk. In order to predict the damage of AASI to the renal function of patients with essential hypertension, the prediction of AASI based on stepwise Regression equation scanning for renal function damage in patients with essential hypertension is proposed. Measure the 24 h ambulatory blood pressure of the selected subjects, establish a linear Regression equation scanning, and calculate the slope of the straight line, and finally, the slope is AASI. According to the quartiles, AASI is divided into four parts: group I < 0.53 ( = 49); 0.53 ≤ group II < 0.60 ( = 51); 0.60 ≤ group III < 0.69 ( = 48); group IV ≥ 0.69 ( = 44). Experiment result shows the following: with the increase of AASI, cystatin (CysC) also increased significantly, while CysC-eGFR decreased significantly ( < 0.05). Compared with groups I, II, and III, Scr and CysC in group IV increased ( < 0.05), and Ccr, CysC-eGFR, and (CKD-EPI)-eGFR all decreased ( < 0.05). AASI is positively correlated with CysC performance, and the correlation coefficient is 0.637. It is negatively correlated with Ccr performance, and is -0.361. It is negatively correlated with CysC-eGFR, and is -0.698. And it is negatively correlated with (CKD-EPI)-eGFR, and is -0.331. Age and 24 h PP also showed an increasing trend with the increase of AASI, and it suggests that age may be an influencing factor that promotes kidney damage caused by hypertension; it also suggests that AASI can be used as a new indicator of arterial compliance; AASI is linearly related to various indicators of renal damage and can be used as a predictive indicator of renal damage caused by essential hypertension; cystatin C and the estimated glomerular filtration rate CysC-eGFR based on cystatin C are better than other indicators reflecting glomerular filtration rate, more sensitively assess the degree of early renal damage. Obesity may also be a factor that promotes kidney damage caused by hypertension.

A predictive method based on a linear equation was proposed to study the factors influencing lower urinary tract dysfunction in Parkinson's disease. A 10-month follow-up of 200 selected Parkinson's patients from January to December 2020 used a linear regression equation to analyze whether depletion function was associated with a specific nonmotor function loss, and a linear regression equation was used for analysis. A loss of emptiness function was used to determine whether there are complications associated with lower motor function and cognitive function. The experimental results showed that dysuria in Parkinson's disease was related to the following nonmotility disorders: gastrointestinal dysfunction (OR 2.52, 95% CI 1.57-3.92, < 0.001), cardiovascular dysfunction (OR 2.31, 95% CI 1.23~4.11, = 0.014), respiratory dysfunction (OR 1.72, 95% CI 1.32~3.24, = 0.029), cutaneous autonomic dysfunction (OR 1.91, 95% CI 1.15~3.08, = 0.023), and sleep disorders (OR 2.01, 95% CI 1.32~3.14, = 0.001). In addition, dysuria was associated with higher UPDRS-III (regression coefficient 1.74, 95% CI 0.56-2.67, = 0.001). Thus, nonmotor disorders have been shown to be associated with early impairment.

Explore the pathogenesis and influencing factors of adult hypertension based on structural equation scanning. Using a multistage random sampling method, randomly select 2 community health service centers in each administrative area of a certain city and conduct a sample survey of residents in the community. According to the predetermined sample size , multiply by 1.3 (1.3) to draw a sample. Community doctors and medical students who have been uniformly trained form an investigation team draw up a questionnaire by consulting the literature, seek expert opinions, and then make changes based on the questions in the preinvestigation. Experiment result shows that the average systolic blood pressure of the experimental subjects was 126.13 + 15.36 mmHg and the average diastolic blood pressure was 79.52 + 8.81 mmHg; males are higher than females and increase with age. The prevalence rate of hyperemia is 26.3%, and the prevalence rate of prehypertension among the survey subjects is 55.4%; that of males (62.6%) is higher than that of females (49.2%). The prevalence of isolated systolic hypertension was 7.5%, and that of men (6.9%) was lower than that of women (7.9%). The awareness rate of hypertension was 66.5%, and the treatment rate of hypertension was 62.7%; the control rate of hypertension was 13.2%, and the control rate of hypertension treatment was 25.7%; all the abovementioned rates are higher for women than for men, and they all tend to increase with age which proved that being overweight is a risk factor for hypertension, dyslipidemia, and hypertension. Hypertension, dyslipidemia, and family history of hypertension are risk factors for hypertension. There is a positive correlation between hypertension and dyslipidemia.

To study the effect of football injury on knee pain based on MRI image scanning, in this paper, a total of 31 knee injuries of 29 male professional football players from December 2012 to April 2015 were used as the experimental group. The players were 23.6 ± 3.5 years old and received professional football training time 15.3 ± 3.6 years; 31 outpatients of the same age group with acute knee joint acute injury were randomly selected as the control group; both groups were imaged with a 1.5 TMR scanner and knee joint standard array coil imaging, and 2 senior radiation surgeons evaluate knee cartilage, meniscus, ligaments, tendons, bone marrow, infrapatellar fat pad, and joint effusions. Pearson's chi-squared test and nonparametric test for two independent samples were used for statistical testing of the evaluation results. The experimental results showed that there were significant differences in the incidence of articular cartilage, lateral collateral ligament, tendon or ligament injury, multiligament or tendon injury, and bone marrow edema between the two groups ( < 0.05). There was no significant difference in the incidence of medial collateral ligament injury, infrapatellar fat pad edema, and joint effusion. MRI shows that knee injuries in male professional football players often involve ligaments or tendons, mostly multiligament or tendon injuries. The lesions of articular cartilage and meniscus are more common and serious, and bone marrow edema is also more common in football injuries. MRI has high diagnostic accuracy for various clinical knee injuries, and it belongs to a noninvasive examination method. It can not only reflect the pathological changes and changes of the knee joints of patients but also provide information for the formulation of clinical programs and the judgment of prognosis, for timely, accurate, and comprehensive imaging reference.

In order to solve the factors affecting the clinical efficacy of meniscus resection, a method based on logistic regression analysis is proposed. From May 2019 to May 2020, 60 patients with discoid meniscus who underwent arthroscopic surgery in the Joint Department of the Second Hospital of a certain city were selected as the research objects; the surgical methods are divided into partial meniscus excision and plasty and total meniscus resection. The Lysholm function score was used to evaluate the clinical efficacy of arthroscopic surgery for discoid meniscus injuries before and 3, 6, and 12 months after surgery and postoperative application of Ikeuchi score and Tegner exercise ability score to assess age, gender, body mass index (BMI), duration of symptoms, and the influence of meniscus injury types and surgical methods on the efficacy of arthroscopic surgery for discoid meniscus injuries. Experimental results show that Ikeuchi's assessment of the excellent and good rate of arthroscopic knee joints was significantly higher than that of the control group, the incidence of postoperative pain was significantly lower than that of the control group, and the difference was statistically significant ( < 0.05). Postoperative pain and premature weight-bearing of discoid meniscus injury of knee joint, factors such as noncold compress after operation, articular cartilage damage, age, and time from onset to operation are closely related; the difference was statistically significant ( < 0.05). Postoperative evaluation according to Ikeuchi score: excellent in 38 cases, good in 14 cases, 8 cases were poor, and the excellent and good rate was 86.7%. The patient's age, type of meniscus tear, and duration of symptoms have a certain impact on the postoperative clinical efficacy of discoid meniscus injury; BMI and surgical methods have no significant impact. Logistic regression analysis results show that postoperative pain and premature weight-bearing of discoid meniscus injury of the knee joint, no cold compress after operation, accompanied by articular cartilage damage, age, and factors such as onset to operation time are closely related; the difference was statistically significant ( < 0.05). It proves that arthroscopic surgery for discoid meniscus injury has the advantages of less damage and faster recovery, it is the first choice for the treatment of discoid meniscus injury, and the postoperative effect is significant in young patients and those with short duration of symptoms; mixed tears have a greater impact on the postoperative recovery of patients with discoid meniscus injury; therefore, patients with discoid meniscus injury should undergo surgery as soon as possible and perform active rehabilitation exercises after the operation.

This paper analyzes the factors of peripheral neuropathy in type 2 diabetes mellitus and puts forward a balanced analysis of peripheral neuropathy in type 2 diabetes mellitus based on logistic regression equation. A total of 1192 eligible patients were selected as the study subjects. All selected patients underwent 75 g oral glucose tolerance test to measure fasting blood glucose and insulin and 2-hour postprandial blood glucose and 2-hour postprandial insulin, as well as neuroelectrophysiological examination. The results showed that the OR values of age, course of disease, fingertip blood glucose immediately after admission, and 2-hour blood glucose were greater than 1, and the values were all less than 0.05, which were the risk factors of diabetic peripheral neuropathy. OR value of cell function index (HBCI) is less than 1. is less than 0.05, and it is a protective factor of diabetic peripheral neuropathy. Laboratory indicators are as follows: 75 g OGTT: 0-hour blood glucose, 2-hour blood glucose, and glycosylated hemoglobin; serum creatinine; glutamate transaminase; fibrinogen; ten items of hemoglobin; and indexes reflecting islet function: islet is thin, and there are significant differences in cell function index, insulin resistance index, and insulin secretion index between the non-DPN group and DPN group. Age, course of disease, fingertip blood glucose immediately after admission, and blood glucose within 2 hours after admission were the risk factors for diabetic peripheral neuropathy. Islet cell function index (HBCI) is a protective factor of diabetic peripheral neuropathy.

In order to explore the clinical characteristics of hemodialysis in curing poisoning from snakebites, a two-classification model of nuclear logistic neural network based on restricted Boltzmann machine is proposed. The model combines kernel logistic regression with artificial neural networks, enabling the model to both learn autonomously and handle linearly inseparable problems. The network first performs feature learning through unsupervised training of restricted Boltzmann machines and obtains the initial values of the parameters to be identified, which reduces the influence of the randomness of the initial parameters. The variable universe learning rate with scaling factor is used to learn the parameters to be identified, and the model convergence speed is improved by dynamic adjustment of the learning rate. Experimental results show the following: Compared with before treatment, patient's activated partial thromboplastin time (APTT) after treatment and the prothrombin time (PT) level decrease, fibrinogen (FIB) levels are elevated, aspartate transferase (AST) and creatine kinase isoenzyme (CK-MB) level decreased, and the differences were statistically significant ( < 0.05). It is proved that continuous hemodiafiltration combined with plasma exchange treatment can effectively improve the blood coagulation index and myocardial index of severe snakebite poisoning patients.

OBJECTIVE: In order to explore the effect of rehabilitation training based on automatic extraction algorithm on knee anterior cruciate ligament reconstruction under arthroscopy. METHODS: 81 patients with anterior cruciate ligament injury were randomly divided into observation group (42 cases) and control group (39 cases). The control group was given routine nursing, while the observation group was given rehabilitation training guidance based on automatic extraction algorithm. Lysholm score, HSS score, and range of motion of knee joint extension and flexion were used to evaluate the knee joint function before and after operation in the two groups. The quality of life of the two groups was evaluated by the concise health survey scale. The results showed that 50% of deep venous thrombosis occurred on the first day and 30% on the second day after operation. There was no significant difference in preoperative Lysholm score, HSS score, and knee flexion activity between the observation group and the control group ( > 0.01). After 1-month, 5-month, and 1-year follow-up, the effective rate of knee function recovery in the observation group was significantly better than that in the control group. Lysholm score, HSS score, and knee extension and flexion activity were significantly different from those in the control group ( < 0.01). The postoperative SF-36 quality of life score of the observation group was significantly higher than that of the control group, indicating that the quality of life of the observation group was significantly better than that of the control group. Therefore, early postoperative rehabilitation training guidance based on automatic extraction algorithm can improve local blood circulation and improve knee function and reduce pain, so as to promote the early recovery of patients.

INTRODUCTION: Mindfulness cognitive therapy is based on mindfulness decompression, integrating the elements of cognitive behavioral therapy and related psychological education components, a set of mindfulness group courses designed. OBJECTIVE: In order to explore the influence of mindfulness training on fluency and anxiety in shooting sports training. METHODS: There are 22 athletes in a provincial shooting team, 12 in the experimental group and 10 people in the control group, grouped according to the random principle. A single-participant experiment design with multiple baseline levels of ABA was adopted. RESULTS: The fluency state of the athletes has increased from 28.75 to 30.63; the average value before the intervention increased by 6.5%, PEM = 88%, explaining that the previous intervention has a moderate-intensity effect. The average value of athletes' sports competition anxiety state 205 before intervention was reduced to 171.25, reduced by 16.5%, PEM = 100%, showing that the intervention effect is very effective. CONCLUSIONS: After the shooting athletes received the intervention of the mindfulness cognitive intervention method MBCT, the state of fluency is improved, the level of competition anxiety is reduced, and the experimental intervention basically confirmed the research hypothesis. This study confirms the moderating role of emotion regulation self-efficacy between mindfulness and the fluency of shooters and provides further impetus for the refinement and development of a push-up spiral model that explains mindfulness mechanisms.

In order to explore the regression equation for the prediction model of subarachnoid hemorrhage and cerebral vasospasm, the nomogram prediction model of SCVS occurrence was established. This study is a retrospective analysis of 125 cases of aSAH admitted to a hospital; the patients were divided into SCVS group and non-SCVS group. Select SIRI as a simple and reliable marker of inflammation, analyze its correlation with SCVS and its predictive value, and analyze the predictive value of SIRI to SCVS through ROC curve. Based on the SIRI inflammation level and other related risk factors, a nomogram prediction model for the occurrence of SCVS was built. The experimental results show that the SIRI level of patients in the SCVS group was significantly higher than that of the non-SCVS group, and logistic regression analysis found that SIRI is an independent risk factor for SCVS. = 3.63 × 10/ is the best cutoff value for diagnosing the occurrence of SCVS. When TC = 2.24 mmol/L and SIRI = 3.63 × 10%/L, its Youden Index is the largest (0.312, 0.296) and is the best cutoff value for predicting the occurrence of SCVS; at the same time, its prediction accuracy (area under the ROC curve (AUC)), sensitivity, specificity, the positive predictive value, and negative predictive value are 0.743, 72.70%, 80.10%, 77.53%, and 94.24% and 0.725, 70.60%, 76.90%, 73.49%, and 93.59%. Nomogram prediction model establishment and evaluation combined with the results of multifactor analysis are used to build an individual nomogram prediction model. The model has good prediction consistency (C-index = 0.685, < 0.01). ROC analysis results showed that the model that combined SIRI and other standard variables (AUC = 0.896, 95% CI was 0.803-0.929, < 0.001) was better than the model that did not combine SIRI (AUC = 0.859, 95% CI was 0.759-0.912, < 0.001) and the model based only on SIRI (AUC = 0.725, 95% CI was 0.586-0.793, = 0.001) has better predictive value for SCVS. Joint SIRI will optimize the prediction performance of the nomogram model and improve the early recognition and screening capabilities of SCVS.

In order to explore the clinical point selection rules of acupuncture and moxibustion in the treatment of infantile enuresis based on data mining technology, first, it introduces the principle of data mining technology, the global optimization strategy of information extraction + genetic search. In China Biomedical Literature Database, CNKI, Weipu, Wanfang. Use "enuresis," "enuresis," "leathering," "urinary discharge," "drowning," "bedwetting," "nocturia," "drowning," "moxibustion," "moxibustion," and "moxibustion" as search terms, take (enuresis + enuresis + urination + urination + addiction + bedwetting), (moxibustion + moxibustion + moxibustion)" as the retrieval style. The analysis of the use of moxibustion, the law of acupoint selection by different moxibustion methods, and the frequency analysis of meridian use show that most of the moxibustion methods are used (62 articles, of which 3 articles use 2 moxibustion methods), including non-suppurative moxibustion, ginger moxibustion, medicinal cake moxibustion, salt moxibustion, mild moxibustion, warm acupuncture moxibustion, bird pecking moxibustion, circling moxibustion, and warm moxibustion; among them, mild moxibustion has the highest frequency of use 24 and non-suppurative moxibustion and salt-separated moxibustion have the lowest frequency of use1; there are 4 non-moxibustion methods, which are medicated thread moxibustion methods. Different moxibustion methods for acupoint selection have their own emphasis. The 63 included literatures included 63 prescriptions for moxibustion, 11 prescriptions for acupoints. Analyzing the frequency of acupoint selection, a total of 18 ear acupoints are involved, and the total frequency of auricular acupoints is 54 times; 44 points are involved (including 1 odd point outside the meridian), the total frequency of acupoints is 300 times, and the total frequency of meridian points is 298, and the total frequency of Jingwaiqi acupoints (Sishencong) is 2. The results can provide great help for the clinical selection of acupuncture points for the treatment of infantile enuresis.

Endodontic treatment is basically dependent on knowledge of the root canal anatomy. The goal of this study was to use cone-beam computed tomography (CBCT) imaging to examine the C-shaped canal configuration of mandibular and maxillary second molars in an Iraqi subpopulation. The prevalence and configurations of C-shaped canals were evaluated in 368 mandibular second molars and 369 maxillary second molars using CBCT scans. The effects of gender, age, and unilateral/bilateral on the presence of C-shaped canals were investigated. Chi-square and Fisher's exact tests were used to determine the level of significance ( ≤ 0.05), and kappa value was used to check reliability of results of the research. In mandibular second molars, the prevalence of C-shaped canals was 17.4%. The prevalence was significantly higher in females (23%) than males (10.4%) using the chi-square test. There is no significant difference in the prevalence of C-shaped canal depending on age and tooth position. The C2 type was the most common (56.3%). This prevalence did not differ with gender, age, or tooth position. In maxillary second molars, C-shaped canals were present in 7.9%. Type I (subtype C) (fusion of 2 root canals MB-DB) was the most common type of fused root (65.5%). There is no significant difference in the prevalence of C-shaped canal depending on the type of fused root, age, and tooth position. The majority of C-shaped canals in mandibular second molars were bilateral in both genders, but unilateral presence was more common in maxillary second molars in both genders. Within the limits of this study, C-shaped canals were found to be more common in mandibular second molars than in maxillary second molars in an Iraqi subpopulation.

Scanning transmission electron microscopy (STEM) developed into a very important characterization tool for atomic analysis of crystalline specimens. High-angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) has become one of the most powerful tools to visualize material structures at atomic resolution. However, the parameter of electron microscope and sample thickness is the important influence factors on HAADF-STEM imaging. The effect of convergence angle, spherical aberration, and defocus to HAADF imaging process has been analyzed through simulation. The applicability of two HAADF simulation software has been compared, and suggestions for their usage have been given.
